I currently have 15 mixed Bantams that were born Oct. 21, 2012. I also have 4 Seramas that were born Nov. 29. The Bantams have been out in the coop & yard-ranging since right before Christmas. This week we are having sunny weather so this is what I did with the Seramas to try to get the 'flocks' to co-mingle successfully. I let the Bantams out in the AM as usual. I put the Seramas into the coop and shut the pop door. At 5:45p, when the Bantams normally go to 'bed', I went out and opened the pop door and they all trouped inside with the Seramas and went to bed. Repeat today -- same schedule. I didn't allow the Seramas to come out in the morning into the yard. So they've been in the coop now 2 full days and with the Bantams at night and early in the morning. I haven't noticed any pecking, bullying, etc. except the Seramas have tended to stay on the very top roost bar when I've peeked into the window at night. Do you think I need to do this another day or two (keep the Seramas locked in the coop during the day?) or should they be OK now to leave the pop door open and let them come out if they wish?
